Same root cause as the earlier Windows exe icon fix: add_executable()
never set MACOSX_BUNDLE, so on macOS this produced a bare Mach-O binary
rather than a proper .app bundle -- and without a bundle there's no
Info.plist/.icns mechanism for Finder to show a custom icon at all.
Added packaging/macos/orbithub.icns, rendered at up to 1024px directly
from the same createOrbitHubAppIcon() logic used at runtime (via a
one-off export tool, not committed) so it matches what the app actually
looks like. CMake's MACOSX_BUNDLE keyword and MACOSX_BUNDLE_ICON_FILE
wire it into an auto-generated Info.plist; both keywords are no-ops on
other platforms. The profile database uses QStandardPaths::AppDataLocation,
not the executable's own path, so this doesn't affect where existing
profiles are found.
Build output on macOS changes from build/orbithub to build/orbithub.app
(launch with `open build/orbithub.app`); docs/BUILDING.md updated to match.
